I have custom dockerfile and also have add expose 80/tcp in Dockerfile
The TargetPort 80 does not match the listening port 9001. The TargetPort 80 does not match any of the listening ports: [9001 9000].
I also tried to run in my local port expose were there
However I always getting an error while want to bind port 80 in container apps
anyone know what exactly missing from my config, or its a bug from azure?

As stated, /called out in this documentation, you cannot make your container app to run on port either 443 or 80 for TCP.
You can refer to sample docker file of container app : https://github.com/Azure-Samples/containerapps-albumapi-csharp/blob/main/src/Dockerfile
Hope this helps, let me know if you have any further questions on this.

Azure should detect this delay and not deny it. need to inform azure team about this

Amit Dave 0 Reputation points2025-05-02T11:56:33.68+00:00 The TargetPort 8080 does not match any of the listening ports. Trying to deploy keycloak, and image exposes 8080 port however seems container app not able to handle that with the ingress configurations.
"The TargetPort 80/8080/9000 does not match any of the listening ports: [43099 24000 41967]." dont know from where these other port details are displayed in the error message.
Tried with different ports from the image such as 9000/8080/etc. but no luck, request MS to either provide details properly or let container app interface display the public images' configurations so that one can know about the details. Seems there is no way one can use container app if it continues to hide details and throwing such errors.
